置。[Claims for Utility Model Registration] (1) A powder toner image is fixed by a heat roller having an internal heating source and a pressure roller brought into pressure contact with the heat roller, and the surface temperature of the heat roller is controlled by a controller. In a fixing device of a copying machine, the surface temperature of the heat roller is controlled to be a first set temperature after the power is turned on until the copying operation is started, and after the copying operation is started, the surface temperature of the heat roller is controlled to be the first temperature. The fixing device for a copying machine is characterized in that the controller is provided with a function of controlling the temperature to a second set temperature that is lower than the first set temperature. (2) The method according to claim (1), wherein a timer is incorporated so that the period for controlling at the first set temperature is extended for a certain period of time after the start of the copying operation, and thereafter the control is performed at a second set temperature lower than the first set temperature. Copying machine fixing device.
